Alzheimer’s disease is characterized by the buildup of a toxic protein called tau that damages and eventually destroys brain cells. The disease progresses as this harmful protein moves to new areas of the brain, worsening memory loss and cognitive decline. This time, researchers discovered an unexpected person in the process. A study in mice found that a brain protein called Arc, which normally helps neurons communicate, also appears to help toxic tau spread from diseased brain cells to healthy brain cells. The findings suggest a potential new strategy to slow Alzheimer’s disease. Rather than trying to eliminate tau completely, future…

When humans walk freely in open or enclosed spaces, they naturally tend to turn in a counterclockwise direction. This individual bias provides evidence that essential individual tendencies shape the way large crowds organize spontaneously. These findings published in the journal nature communicationsproposes a new way to understand human movement. In studying pedestrian dynamics, scientists observe how large groups move together in shared spaces. In crowded places, people often spontaneously form opposing lanes or take turns like zippers when passing through narrow doorways. These patterns are known as emergent behavior. Emergent behavior occurs when simple actions taken by individuals combine to…

This month, a fire at the massive Lineage cold storage warehouse in Boyle Heights caused a spike in the number of Angelenos visiting hospitals with sore throats and concerns about smoke inhalation, the Times reported. The fire burned for eight days starting June 17, burning solar panels, insulation foam and other industrial materials. During that time, more than three times as many people visited emergency departments within 10 miles of the warehouse with complaints of fire or smoke inhalation than two weeks earlier, according to Los Angeles County Department of Public Health data obtained through a public records request. The…

The Environmental Protection Agency will not require public water utilities to test drinking water for microplastics or pharmaceuticals for the next five years, according to a proposed rule published in the Federal Register. On Friday, the EPA submitted a list of chemicals it plans to test under the Unregulated Contaminants Monitoring Rule, a mandatory testing program used to gather information about chemicals in drinking water that can pose a hazard to human health. Contains no microplastics or pharmaceuticals.The omission came after EPA Administrator Lee Zeldin announced earlier this year that the agency was designating priority contaminants in microplastics and pharmaceuticals…

A provision in the two-year state budget finalized by the Legislature on Monday imposes a new tax on data centers, Virginia’s most energy-intensive industry. Virginia General Assembly approves Spanberger’s budget amendment, ending months of gridlock The spending plan maintains sales and use tax exemptions for data centers, the focus of a lengthy legislative battle over the past several months. But the new tax represents the state’s first major effort to recoup millions of dollars from the industry, especially for energy use, and address residents’ concerns about the rapidly increasing number of facilities. “We have more data centers than anywhere else…

The chaotic chaos on Delhi’s roads would be unrecognizable without the millions of rickshaws and scooters that continue to zip through India’s capital, spewing toxic fumes. But now, an ambitious policy is underway to bring an environmental makeover to the city’s most famous car.The Delhi government on Monday announced plans to eventually ban petrol scooters, motorbikes and autorickshaws in favor of electric-powered ones in a bid to bring down dangerously high pollution levels in the city by the end of the decade.The policy, which will phase out new petrol and gasoline-powered scooters, trucks and buses in the capital region over…

This article is Updated with comments from the White House. The “Make America Healthy Again” movement hopes to have no enemies. Over the past two years, seed oils, sugary drinks, pesticides, pharmaceuticals, childhood vaccines, and the industries that support them have come under unprecedented scrutiny. But MAHA’s quest to overcome the root causes of chronic disease omits an obvious enemy: alcohol. The movement and its leader, Robert F. Kennedy Jr., have largely avoided alcohol, even though alcohol causes more deaths in the United States each year than infectious diseases and opioids combined. A STAT investigation found that the Trump administration…

Scientists often visit remote forests, mountains, and islands in search of undiscovered species. But in a surprising development, researchers at Kyushu University have discovered that a previously unknown ladybug lives in pine trees right near the university’s campus. The name of the newly identified species is Parastesolus pinicolawas discovered by the Kyushu University Hakozaki satellite. This finding was reported in Entomology Journal of the National Museum of Prague The study grew out of a three-year project investigating the taxonomy of stesolini, a group of small ladybugs that feed on spider mites. This study is the first large-scale investigation of this…

Vermont just delivered the largest number of super-efficient homes. This is the latest example of how a pioneering state program can reduce utility costs for residents of this type of affordable housing. All-electric homes equipped with heat pumps reduce energy use by more than half compared to conventional new construction homes. To accomplish this feat, each home meets rigorous specifications under the Advanced Manufactured Homes Program created by the state’s energy efficiency company Efficiency Vermont. 2024. This standard is not mandatory. It is up to the federal government to regulate the efficiency of manufactured homes. Instead, the Vermont Initiative recognizes…

Creatine is one of the most popular sports supplements in the world and is widely used to improve strength and muscle performance. Now, researchers are exploring whether there may be benefits beyond the gym. New systematic review published in brain medicine We investigated whether creatine could help alleviate depression by supporting the brain’s energy needs. While the findings suggest cautious optimism, they also highlight how much remains unknown. While some clinical trials reported significant improvements in symptoms of depression, others found no effect at all, leaving scientists with interesting questions rather than clear answers. Review of clinical evidence Instead of…
